Post-Contract Process Engineer

Key Responsibilities

Translate preliminary pre-contract designs, Process Flow Diagrams (PFDs), and Piping & Instrumentation Diagrams (P&IDs) into finalized, execution-ready process engineering packages.

Perform detailed hydraulics, pump sizing, mass balances, chemical consumption calculations, and equipment line sizing across UPW, reclaim, and wastewater process units.

Review and approve vendor technical submittals, equipment data sheets, instrument specifications, and component selections (e.g., pumps, resin vessels, RO/EDI skids, UV systems, ozone destructors).

Coordinate closely with Mechanical, Piping, Electrical, and Automation teams to resolve technical interfaces and develop process control philosophy.

Assist in pre-commissioning, chemical cleaning/sanitization, flushing, and media/resin loading sequences.

Troubleshoot operational bottlenecks, process instabilities, and analytical anomalies during startup phases.

Serve as the primary technical point of contact for client representatives, owners' engineers, and managing contractors during the execution phase.

Prepare comprehensive operations and maintenance (O&M) manuals, process testing protocols, commissioning procedures, and final validation documentation for handover.
